To all whom 2'25 may concern Be it known that we, WILLIAM S. Losses shire, have invented an Im rovement in Ma-1 chines for Channeling Insoles, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to apparatus for treating insoles and especially. insoles made from fibrous materials in a normally loos condition or pulp and such as now foifind upon the market under the name of fiber board. 7

The present invention has for its object to provide a machine with which insoles and especiallyinsole's madefrorn fiber board may be provided with a channel to form a hpand feather, to enable said insoles to be em= ployed in the manufacture of welted boots and shoes. v 4

The present inventionhas also for its object to provide a machine with which the edge of the insole blank may be slitte'd or cut, so as to form a flap of substantially uni= form thickness and with which the flap may be trimmed or cut off to' narrow the same.

Provision is also made for varying the amount trimmed off from the flap, so that the cut flap which remains attached to the insole may be of substantially uniform width, to enable it to form a lip of substan tially uniform height when tiirned into a" position at an angle to the body portion of the insole. p

Provision is made for feeding the blank insole throught'he machine.

Provision is also made for compressing the insole for a purpose as willbe described.

These and other features of this invention will be pointed out in the claims at the end of this specification. I

Figure 1 is a plan and Fig. 2 aside elevation of one construction of machine em bodyingi this invention: 3, a vertical section on the line 3*-3, Fig, 2-, with parts omitted. ig. 4;, a plan of the machine verted. Figslbland 6, enlarged details to illustrate the channeling and trimming open ations, Figl 7, a detail in plan of a portion of a channeled and trimmed insole blank. Figs. 8, 9 and 10, enlarged details to be referred to, they being a side, lan and rear view, respectively, oftlie bracket 38' and the parts carriedther'eby.

In the present instance we have illustrated one construction of machine embodying the invention, in whicl'l a splitting or channeling knife a is arranged to reciprocate substantially in the plane of the insole blank I) and in a path substantially at right angles to the edge of said blank, so that the knife a cuts into the edge of the insole blank between the upper and lower surfaces of the blank, as thelatter is fed through the machine, as will be described. The reciprocatingknife a cuts or slits the edge of the insole blank '6 and forms a flap 0 and feather d, see 5, and the flap c after being formed the channeling or splitting knife (1/; is subjected to the action of a cutting or trimmin mechanism, which serves to cut or trim of? a portion of the flap so as to form a narrower flap 6, see Figs. 6 and 7, which is designed to form the lip or rib of an insole for use in weltedbo-ots or shoes, and which lip in its operative p'osition extends at an angle to the body portion of the insole. V

In the present instance, the cutting or trimming" mechanism employed to cut off a portion of the flap 0 and form the narrower flap c, shown as a reciprocating knife 12, which is arranged to reciprocate in a path at an angle to the path of reclpro'c'a'tion of the channeling knife, and in the machine hereinshown, the knife 12,

which may be designated the trimming knife, is arranged above the plane in which the knife a reciprocates, and moves in a substantially vertical path, see F igs. 5, 6, 8 and 10; The knives a, 12 are operated by mecha; nism which is: constructed and arranged the machine herein shown,- so as to cause the said knives to act on the insole alter nately', that is, the knife-a on its forward movement slits or channels the insole blank 6 to form the flap 0 and then is inovedbackward in the same plane away from thein sole, and while the knife ais' being with= drawn from the insole, the trimming knife 12 is moved into engagement with the Help 0 to cut off a portion of the same and form the narrow flap e, as represented in Fig. 6, and the knife 12 is then moved away from the insole, and while the knife 12 is-making its backward stroke, the knife a ismaking its forward stroke. Provlslon is made for supporting the insole blank while it is being acted upon by the knives, and also for feeding the blank to the knives. In the present instance, the support for the blank is shown as rotatable and in theform of a wheel 13,

upon the periphery of which the blank I) rests, and the blank is held in firm contact with the rotatable support 13 by a presser tool, preferably a wheel 14,which cotiperateswith the rotatable support 13to feed the blankpast the knives a, 12.

The presser wheel 14 also serves to compress the fibers of the insoleblank in the immediate vicinity of the innermost end of the cut or channel 15 effected by the knife (1,,

and'forms a groove 16, which acts to resist any tendency of the cut or channel 15 being e'xtendedfarther toward the center ofthe insole blank when the flap 6 is turned intoaposition substantially at right angles to the'body portion of the insole to form the lip, which enables the insole to be used in welted' boots and shoes.

The. mechanisms for operating the parts above specified, will now be described.

The channeling knife or, see Fig. 1, is secured as by screws 17 to a carrier shown as a'barlS, which slides in guide ways in stationary bars 19, fastened as by screws 20 to the bed plate 21 of a supporting frame. The

justable connecting rod referred to is shown as composed ofa threaded r0d25, which engages threaded sockets in members 26, 27, pivotally connected with the knife carrier 18 and with the crank pin 22 respectively.

The threaded rod 25 is provided with a collar 28 for engagement with a wrench or other tool by means of which theoperator can lengthen or shorten the connecting rod,

, and thereby adjust the length of the stroke of the channeling knife a, and thereby determine the depth of the cut or channel made in the edge of the insole blank Z).

In the present instance, the trimming .knife 12 is reciprocated from thecrank shaft 23 and as herein shown, the knife 12, see Fig. 2, is secured to. a carrier, shown as a bar 30 which is vertically movable in guide ways in arms31, 32 of a substantially U shaped frame 132, (see Figs. 8, 9 and 10).

In the present instance, the frame 132 has a sidewall 133 attached to a bracket 33, which 1s erected upon thebed plate 21 and secured thereto as ,by screws 34, see Fig.

lever- 35, pivoted betweenthe side walls of a slot 134 in the rear portion of the frame 132, and having one arm 36 connected by a pivot pin 37 with cars 38 on the knife carrier 30, and having its other arm 39 joined by a connecting rod with the carrier 18 for thechanneling knife 0:, the pin '37 passing through a slot 360 in the arm 36. The connecting rod just referred to is adjustable, and for this purpose it is provided with a threaded rod 40, which engages threaded sockets in members 41, 42, the member 41 being pivotally connected with the arm 39 of the bell crank lever, and the member 42 being pivotally connected with a lug 43 on the carrier 18. By adjusting the threaded rod 40 into. or out of its sockets in the members 41, 42, the stroke of the trimming knife 12 can be varied, so as to regulate the depth of the cut made in the insole, and thus prevent the knife 12 penetrating into the feather d of the insole blank, which would not be desirable as the feather would be thus weakened.

By reference to Fig. 2, it will be seen that as the carrier 18 for-the channeling knife (1 is moved toward the work, in the direction indicated by the arrow 45, the arm 39 of the bell crank 35 is moved in the same direction, and the carrier 30 for the knife 12 is moved away from the work in a plane at an angle to the plane in which the carrier for the channeling knife is moved. In other words the knives a, 12 are alternately moved into engagement with the work, the channeling knife enteringthe edge of the insole blank 5 to cut the channel 15 as the trimming knife 12 is moved away from the upper surface of the insole blank and vice versa. The insole blank while being cut by the knives a, 12 is pressed down on the movable supportor roll 13 by the pressure wheel 14, and the support or roll 13 is positively rotated, which is accomplished in the present instance by mechanism as will now be described.

The roll 13 is located below a raised front portion 50 of the bed plate 21, with a portion of its periphery exposed by a slot or opening 51 in the portion 50 of the bed plate. The roll 13 is fast on a shaft 52, see Figs. 3 and 4, having bearings in the framework of the machine and provided with a worm gear 53, which meshes with and is driven by a worm 54 on a shaft 55, journaled in the framework of the machine and having onit a large gear 56, which meshes with a pinion 57 on a stud shaft '58, provided with a pulley 59, which is connected by a belt 60 with asmaller pulley 61 on the main or driving shaft 2 3, which lattermay be rotated in anysuitable manner, and is shown as provided with a fast pulley 62 and a loose pulley 63.

The'supporting roll 13 cofiperates with the pressure wheel 14 to feed the insole blank to the cutting knives, and the periphery of the roll 13 maybe knurledfor a portion of its width to obtain a better grip upon the insole blank. The =upper -feed wheel 14- may be positively driven or as herein shown it may be free to turn on a stud or shaft 65, supported by a vertically movable carrier or bar 66, which is arranged to slide in guide ways incross bars 67, 68, detachably connected with ithearms 31, 32 bysc-rews 230 or otherwise, and is retained in said guide ways by plates or bars 69, 70, which are secured to the cross bars 67, 68 by screws 71 or otherwise. The slide bar 66 is provided on its rear side with a lug 72, which engages the lower cross bar68, to limit the downward movement of the carrier bar 66 caused by a spring 73, whose pressure can be regulated by a screw 7%, extended through the upper cross bar 67.

The carrier or bar 66 is connected at its upper end by a link 76 to one end of a lever 77, pivoted in an upright 78 on the frame 132, and having its other end connected by a link 79 to a foot treadle or levernot shown, by means of which thelever 77'can be moved so as to elevate the bar 66 and the upper feed wheel 1 1, against theaction of the spring 73, and thus lift the feed wheel 14: away from the support or roll 13, when it is desired to place the insole blank in proper position :to the knives or remove the slitted blank from the machine.

The machine is provided with a gage for positioning :the edge of the insole blank with relation to the channeling and trimming knives a, 12, sothat the portion or strip of the flap 0 which is removed by the trimming knife 12, may be varied according as it is desired by the shoe manufacturers to havethe lip on the insole at a greater or less distance from the edge of the insole. In the present instance, the gage is shown as a plate 80, see Figs. 1 and 2, attached to or forming part of a block 81, located above the bed plate 21 and having an arm or por tion extended down through a slot in the bed plate 21 and connected with plate 83, see Fig. 4c, located below the said bed plate. The 1plate83 slides in guide Ways in thesides of guide bars 84:, see Fig, 4:, which are securedto the underside of the bed plate .21 by screws 85 orotherwise.

The sliding plate 83 is actuated by a bell crank lever '86, located below the bed plate and pivoted .at 87 to one of the guide bars 8 1. The lever 86 has its short arm 88 eX- tended over the sliding plate 83 and provided with a slot 90 into which extends a pin 91 on ;a :bar 92, which is adjustabl-y sea sliding cured to the sliding plate 83, by screws 94: which pass through slots 95 in the bar 92. The slots 95 extend transversely of the bar 92, so that the latter can be moved transversely of the sliding plate 83, and thereby move the pin 91 in the slot 90 in the lever 86 and bring said pin nearer to the pivot for the :lever 'or move it away therefrom, and thus lengthen or shorten the stroke or movement of thesliding plate 83 which carries the gage 81. The lever 86 has its long arm extendedthrough a slot 96 in the front side of the framework of the machine, so as to be accessible to the operator, who can move the lever 86 from one end of the slot to the other, and thereby move the gage 80 from its extreme position back of the cuttingedge of the knife 12 to its most forwardposition in close proximity to said cutting edge. Provision is made for looking the lever 86 in positions between these two extreme positions, and for this purpose, the portion of the lever 86 which projects in front of the frame of the machine, is provided with a hole through which extends a locking pin 98, which is adapted to have its lower end enter one of a plurality of holes in a plate-99, see Fig. 2, detachably fastened to a block or shelf 100, which is detachably secured to the frame of the machine by screws 101 with its upper surface flush with the bottom wall of the slot 96, through which the lever projects.

The pin 98 has cotiperating withit a lifting lever 103, which is pivoted at 10 1 to the lever 86 and has its front end forked to en gage the underside of a head 105 on the looking pin, and the rear end of said lever is acted upcn by a spring 106 to normally force the locking pin downward and cause it to remain in one of the holes in the plate or ar 99, until removed by the operator depressing the rear end of the lever 103, so as to lift the locking pin out of a hole in the plate 99. When the locking pin 98 is elevated, the lever 86 can be turned on its pivot so as to move the gage forward or backward with relationto the cutting edge of the trimming knife 12, and thereby permit the insole blank to be bodily moved with relation tothe knives, so that, the channeling knife will penetrate more or less into the insoleffrom the edge thereof, and make a channel which is of greater or less, depth, and so that the trimming knife will cutthe flap c-farther from or near to the edge of the insole blank, as desired by the manufacturers.

In most instances, if not all, it isdesired by the shoe manufacturers, that the lip of the insoleformed by turning up the flap 0 should be removed from the edge of the insole a greater distance at the shank portion of the insole than at the fore part and toe,

and this is accomplished by the operator manipulating the lever 86 so asto properly position the'gage as the insole blank is run through the machine.

Provision is madefor firmly holding the insole blank at its edge while the trimming knife is cuttingthrou'gh the channel flap 0, and for this purpose, a presser plate 110 is supported on the gageSO and is provided with a foot 112 which projects forward, see Fig. 1, and extends over the supporting roll 18 so as to engage the upper surface of the insole blank and hold the-edge of the blank down on the said roll. The presser plate 110 is held down on the gage by a spring1l3 encircling a screw 114, which is extended through a hole on the presser plate and en-. gages a socket in the gage. The spring 113 permits the presser foot to lift so as to compensate for insoles of different thicknesses.

The operation of the machine may be briefly described as follows: The operator setsthe gage 80 in its extreme back position trimmed by theknife 12, which latter recip- 40. 1 trimmed off by the knife 12.

rocates in aplane at an angle to the plane in which the channeling knife reciprocates. As the insole blank progresses through the machine, the operator manipulates the lever 86 to position the gage and vary the width of the portion of the channel flapc which is It will be understood that the operator guides the insolo blank as it progresses through the machine and turns the same to present the toe portion to the action of the knives. V

The machine herein shown is especially adapted for treating or acting upon insole blanks made from fibrous stock of all kinds and especially what is known as fiber board, and the machine effects a clean cut and does I not tear the stock, which is especially advantageous in treating fiber board blanks, as the board is usually made up of layers which are capable of being separated one from the other. The machine is also capable of cutting fiber board blanks which are reinforced by a canvas or other, layer before being presented to the machine, which is advantageous. v

If in the operation of the machine, the operator should desire to reinsert the treated insole so as to correct any error or imperfection in the work at a given point in the treated insole, he can lift the feed wheel 14 by depressing the foottreadlewith which the lever 77 is connected, as above described, and reinsert the insole at the point where he desires to re-treat it. The groove 16 also forms a bending point on which the channel flap is easily bent to form the lip on the in sole.

\Ve have herein shown one construction of machine embodying the invention but it is not desired to limit the invention to the particular construction shown.
